A commercial biscuit sample was included in the study for comparison. Evaluations were carried out using a panel of judges, and attempts were made to relate panel evaluation with instrumental measurements on texture. Hedonic Rating, Texture Profiling, Flavour Profiling and Quantitative Descriptive Analysis were the sensory methods used, while the J.J. Lloyd Texture Testing Machine Model T5K ,was the instrument used for measurements of breaking strength. Differences in texture between experimental and commercial biscuit samples could be detected by the trained panels (p < 0.05). The amount of force required to break the experimental biscuits ranged from 4.2 to 5.8 Newton while a higher force (13.2 Newton) was required to break the commercial biscuit sample. There was a good correlation between trained panel evaluation and instrumental measurements. The experimental biscuits were judged to be more crispy, more crunchy, more crumbly and more gritty as compared with the commercial sample. Products made with shortenings containing palm oil and butterfat were not significantly different in flavour from those made with 100% butterfat. However, there was a significant difference in flavour (p<0.05) between experimental and commercial short-dough biscuits.

Some formulations were selected for pilot plant shortening production. These included 1:40% palm stearin (PS) and 60% AMF; 2:80% interesterified palm oil (IEPO) and 20% AMF; and 3:60% hydrogenated palm oil (HPO) and 40% AMF. Consistency of the shortenings upon storage was measured. Performance evaluation carried out included measurements of creaming properties and cake baking tests. In general, the consistency of shortenings 1 and 2 was stable within the first month but became harder during the second month. On the other hand, shortening 3 steadily became firmer during the 2 months’ storage. Creaming performance of the shortenings improved with storage and shortening 2 showed the best performance. Specific volumes of cakes made with shortenings 1, 2 and 3 after 2 weeks of storage were 97% and 102% of the control cake respectively. Among the three shortenings, shortening 3 showed the best baking performance throughout the two-month evaluation period.
